It may be your intake manifold if they have the same issue that the 2.0 duratec has. They have little runner flaps (kinda like the butterfly valves on a carbeuretor) and those tend to wear out between 80-100k miles. If thats the root of the problem, dont worry about it. Like I said though, i'm not sure that a problem on the Zetecs, it may only be for the Duratecs.

My girlfriend's SPI made a noise similar to what you describe until I replaced the serp, idler, tensioner, timing belt, and water pump. I think it was the water pump pulley. If this is the case, now's your chance to install UDP!

I would check the water pump... Mine was making a rather interesting sound like that, turned out that one of the bolts on the pump pulley had worked it's self lose somehow... I imagine it was because I put to much anti-seize on it... Could be the water pump all together, I believe they are prone to failure on these cars???
